You might remember this effort to craft a Hornby-style level-crossing for the clockwork tinplate from a few months back, using a catalog pic of a 'OO' version found on the net:
Both of the first two attempts proved unsatisfactory for a number of reasons, primarily aesthetics. I looked at a few prewar tinplate gates at York back in April, coming away with a few new ideas.
I made a bunch of changes on Rev. 3.0, including some basic sloping for terrain purposes on either side. I used a friend's recommendation for reducing the grade of the approach, requiring the depth of the piece to be quite a bit greater. Fortunately, I think I can still use the gates I cut for Rev 2.0.
Here's a mock-up for Rev. 3.0, one side only:
The 'OO' version being quite a bit smaller in profile, the pic can be deceiving. It would be tough to achieve that flatter appearance in 'O' without significantly expanding the footprint. Here, there's just not enough ROW to accommodate a deeper approach. The approximate dimensions of Rev. 2.0 were 2" x 5-1/2"; the dimensions of Rev. 3.0 are 3-1/2" x 9". Both are 3/4" high. I'll have to make another for the opposite side, then I can start working on the planned sheet-metal base.
